Question: Explain what changes that allows for the theory to become widely accepted.
For the endosymbiotic theory to become widely accepted, several key changes occurred in the scientific community and through research advancements:
1. Supporting Evidence:
- The discovery of mitochondria and chloroplasts having their own DNA, which is circular and similar to bacterial DNA, provided strong evidence of their prokaryotic origins.
- These organelles also have a double membrane, consistent with the process of one cell engulfing another.
2. Observation of Independence:
- Mitochondria and chloroplasts reproduce independently of the host cell through binary fission, much like bacteria. This independence further supported the theory.
3. Advanced Technology:
- Improvements in microscopy allowed scientists to observe organelles in greater detail, revealing their structural similarities to prokaryotic cells.
4. Molecular Studies:
- Sequencing of mitochondrial and chloroplast genomes showed that their genes are more closely related to bacterial genes than to those of the host cell.
5. Paradigm Shift:
- The scientific community gradually became more open to ideas that challenged traditional views, allowing revolutionary theories like endosymbiosis to gain traction.
These cumulative pieces of evidence and changes in mindset transformed the endosymbiotic theory from a speculative hypothesis to an essential part of our understanding of eukaryotic evolution.
